At the time of our testing (Jan 17, * 2018), there were no known applications which would benefit from fast- * clearing more than just the first slice. * * The fast clear portion of the image is laid out in the following order: * * * 1 or 4 dwords (depending on hardware generation) for the clear color * * 1 dword for the anv_fast_clear_type of the clear color * * On gen9+, 1 dword per level and layer of the image (3D levels count * multiple layers) in level-major order for compression state. * * For the purpose of discoverability, the algorithm used to manage * compression and fast-clears is described here: * * * On a transition from UNDEFINED or PREINITIALIZED to a defined layout, * all of the values in the fast clear portion of the image are initialized * to default values. * * * On fast-clear, the clear value is written into surface state and also * into the buffer and the fast clear type is set appropriately. Both * setting the fast-clear value in the buffer and setting the fast-clear * type happen from the GPU using MI commands. * * * Whenever a render or blorp operation is performed with CCS_E, we call * genX(cmd_buffer_mark_image_written) to set the compression state to * true (which is represented by UINT32_MAX). * * * On pipeline barrier transitions, the worst-case transition is computed * from the image layouts. The command streamer inspects the fast clear * type and compression state dwords and constructs a predicate. The * worst-case resolve is performed with the given predicate and the fast * clear and compression state is set accordingly. * * See anv_layout_to_aux_usage and anv_layout_to_fast_clear_type functions for * details on exactly what is allowed in what layouts. * * On gen7-9, we do not have a concept of indirect clear colors in hardware. * In order to deal with this, we have to do some clear color management. * * * For LOAD_OP_LOAD at the top of a renderpass, we have to copy the clear * value from the buffer into the surface state with MI commands. * * * For any blorp operations, we pass the address to the clear value into * blorp and it knows to copy the clear color. */ static void add_aux_state_tracking_buffer(struct anv_image *image, uint32_t plane, const struct anv_device *device) { assert(image && device); assert(image->planes[plane].aux_usage != ISL_AUX_USAGE_NONE && image->aspects & VK_IMAGE_ASPECT_ANY_COLOR_BIT_ANV); /* Compressed images must be tiled and therefore everything should be 4K * aligned.
